Ecology

Sierra del Tigre is located in the subregion of the Sonoran Desert called the Plains of Sonora[1] along with some example mountain ranges, Sierra Mazatan, Sierra San Javier, and Cananea San Pedro. The threats include urbanization, land clearing, etc. The riparian protected wetland and grassland to the north in the San Bernardino Valley is the San Bernardino National Wildlife Refuge; Leslie Canyon National Wildlife Refuge is also nearby.

People

Home to the Janeros local group of the Nednhi-Chiricahua Apache, who were led by feared Juh in the 1870s, the Sierra El Tigre was one of the last strongholds for fighting Apaches against Mexican and U.S. forces in search of Apache war parties into the 1930s.
